Summer zooplankton distributions at the surface of the outer Bay of Fundy, eastern Canada
Copepods and cladocerans were collected, mainly in August, from the top 0.25 m of the water column in the outer Bay of Fundy, off Brier Island, Nova Scotia (ca. 44°15′N, 66°23′W) in 1975–1978, Deer Island, New Brunswick (ca. 45°00′N, 67°00′W) in 1977–1978, and Grand Manan Island, New Brunswick (ca....
